Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency. The charging power of wireless reverse charging is not very large compared with the original charger of the mobile phone, and the speed of daily charging of large-capacity devices will be slower, which is more suitable for emergency use in emergency situations.
Wireless reverse charging refers to a wireless charging technology. Wireless reverse charging allows devices to charge each other without the use of wires or other connections. This technology is made ofPioneered by Apple, it allows Apple devices like the iPhone, AirPods, and Apple Watch to charge each other. The principle of wireless reverse charging is to use the power of the device itself to charge other devices.
Wireless reverse charging means: The function of using the mobile phone as a mobile power to charge other devices, first connect the two mobile phones with the OTG line and the mobile phone data line, and then change the USB connection mode in the notification bar to reverse charging on the mobile phone on the power supply side.

Wireless reverse charging refers to a wireless charging technology, that is, a device can charge other devices through wireless charging. The core of wireless reverse charging technology lies in wireless energy transmission. Usually, we use a charger or charging cable to charge our phones or other electronic devices. However, with the advancement of technology, some devices already have the capability of wireless reverse charging.
Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves to them through the wireless coilHe supports wireless charging for device charging. However, its charging power is small and can only be used as an emergency. Wireless charging technology (English: Wirelesschargingtechnology; Wirelesschargetechnology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
Wireless reverse charging is to charge other devices that have no power by sending electromagnetic waves through the wireless coil; Both devices should support wireless charging, and can be charged without a data cable; Ordinary emergency useYes, the charging power is relatively small. At this stage, the mobile phones on the market basically support the OTG function, but some low-end machines and individual mobile phones will not support it due to cost constraints.
